Question

Why electrolysis of Ba(OH)2 with Pt electrode would give best yield

Answer 1

Answer:

Doing electrolysis of warm aqueous Ba (OH)2 solution between nickel electrodes is a commercial method to obtain highly pure (99.95%) dihydrogen. In the presence of Ba(OH)2, water dissociates into ions easily and quickly and H+ ions are produced, which go on cathode, gets discharged there and liberate hydrogen gas

Answer 2

$\huge{\mathcal\pink{♡ AnSwEr ♡}}$

» Doing electrolysis of warm aqueous Ba ( OH ) 2 solution between nickel electrodes is a commercial method to obtain highly pure ( 99.95 % ) dihydrogen .

» In the presence of Ba ( OH ) 2 , water dissociates into ions easily and quickly and H + ions are produced , which go on cathode , gets discharged there and liberate hydrogen gas .

» Electrolysis is done in a hard glass tube . Hydrogen is liberated at cathode while oxygen is liberated at anode .
